2. In what month is anthracnose basal rot likely to start infecting the plants?

AprilMayJuneJuly

3. When is the typical month symptoms of anthracnose basal rot will first be evident?

Just after snow meltJuneAugustOctober

4. Pythium root rot is most likely to occur on:

areas with ample sunlight and air flowareas that are cool and moist for extended periodswhen the night temperature exceeds 22 °C and RH is greater than 90% for more than 10 hourson recently aerated fairways and greens

5. The symptoms of Pythium root rot are:

grass is sparse and yellowgrass is slow to break dormancy in the springgrass does not respond to fertilizer applicationsall of the above

7. Are you likely to see the symptoms of take-all patch in the spring?

yesno

8. Summer patch usually infects:

Annual bluegrassFescuePerennial ryegrassCreeping bentgrass

9. Which statement is false?

Runner hyphae can be seen on roots infected with summer patch.Pythium spores are commonly found in turfgrass soil, making this disease difficult to diagnose with lab tests alone.Anthracnose basal rot does not exhibit the acervuli in the early stages of disease development.Take all patch is only associated with USGA greens and newly established turfgrass areas.

10. The two times to treat for summer patch and take all patch include:

when the disease symptoms are evidentin the spring when soil temperature thresholds are reached and in the fall when the soil temperatures are conducive to fungal activityjust prior to the onset of hot and humid conditions in the summerprior to aeration of susceptible areas or areas where there is a history of disease

11. How do you justify the preventative application of a fungicide treatment for control of summer patch or take-all patch under the new IPM Regulations?

Documented history of disease in the area of treatmentMonitoring soil temperatures to determine when fungal infection is likelyDisease risk indicators in GreenCast.caAll of the above
